Subject: Integration of Tomas Hrasky's port of basic GLU NURBS functionality
 from C++ to Java, plus example applications, done as part of his Bachelor of
 Science degree at the University of Hradec Králové, Faculty of Informatics
 and Management.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current state of code is documented in
src/classes/com/sun/opengl/impl/nurbs/README.txt.

Example applications require Java 1.5 and are not currently built by
default. Specify -Djogl.nurbs=1 during jogl-demos build with a 1.5
javac on the PATH to build them. Dependent jars are copied to build
output directory.

Deleted old partially-complete GLU NURBS port.
